WebFeb 20, 2024 · Approach 1: A simple solution is to traverse the input array. As soon as we find a 0, we return n – index of first 0. Here n is number of elements in input array. Time complexity of this solution would be O (n). Space Complexity: O (1) as we are not using any extra space. Approach 2: Since the input array is sorted, we can use Binary Search ...
